Help! 1992 s-10 blazer: no start

[cuthbert]

Got a problem here, can anyone help?

Here's the deal:
Just bought a 92 s-10 blazer, ran okay when I went to test drive it, though I heard a loud whirring when I turned the ignition to ON. My dad thinks it was the fuel pump. Now, no whir, and no start; just turns over endlessly but no start. My dad and my brother are looking at it now, unfortunately I don't know too much about cars; any ideas?

P.S.: does anyone have a wiring diagram that would show the wires going to the fuel pump?

Thanks

Sounds like the fuel pump went bad. Try and check your fuel pressure at the shrader valve located behind the plenum on the driver side. You have 60 - 65psi with the ignition switch on. If nothing and you can't hear the pump priming when you turn your ignition switch on. Then I would say that you need to replace your fuel pump. Good luck. Let us know what you find.

Just so that you know a shrader valve looks just like the fill valve on your tire.
